Half-stop?

[NirreBosse]

Zerogee, That was a good lection in knifeknowledge. Thank you very much. I personally dont think to high about halfstops but your thoughts about wearresistance makes them more interesting and also the fact its easyer to file if one dont taking fluch positions into koncideration.

I've seen really old folders where the springs were rounded at the back, sitting a little higher than the liners. (Makes sense - they typically forged the springs starting with solid wire of a suitable diameter.) This would make getting the spring flush a rather moot point.

Funny that we don't have any images of these things until now

Here is an example I have posted before of what Dwight refered to as a "clean and square" or "flush and clean" joint.

This is a very old knife with the makers mark Harrison Bros & Howsen Cutlers to her Majesty, 45 Norfolk St., Sheffield.

It has a "flush and clean" joint. The tang is flush with the spring, end, and bottom of the knife in all positions. This knife appears to have been made around the antler and the spring was made to match it exactly. Normally handle material is made to fit the frame of the knife, not vice versa. Maybe this was a custom knife out of that shop or possibly this was standard practice at the time for this style of knife

This mark was used between 1847 and 1901. Tony believes this knife was an early one because of its construction and use of the flush and clean joint. F and C joints were used extensively on early slip joints.

Here's another thread with some "square joint" info.

Thanks for posting that old Sheffield Kerry, it's great to be able to see exactly what you're talking about.

It's pretty common for the really old quill knives to have the clean and square construction also. This is a GcrownR Rodgers (pre-1830) with horn scales -- besides the clean and square joint, the other older features it has are a small square kick and forged integral iron bolsters and liners (the extremely short bolsters are another good "this is old" clue -- not for precise dating - but if you see it, look closer). This one floated across the bay in ancient times - I snagged the images. Please pardon the garish background - I didn't do it.

Great thread guys. I was just going to ask about half stops when the search turned this up. I've definitely learned a lot quite quickly. FWIW the Case/Bose swayback jack has great half stops that are flush at the halfway point. Not bad for a $60 knife.
